BUTTON-HOLE-CORDING ATTACHMENT FOR SEWINGMACHINES.

SPECIFIQATION forming part of Letters Patent No, 356,521, dated J'anuary 25, J 887.

Application filed April 20, 1886. Serial No. 199.543. (No model.)

To all whom, it may concern:

Be it known that I, Josnrrr S. COLLINS, a citizen of the United States, residing at Phila delphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Button-Hole- Cording Attachments for Sewing-Machines; and I do hereby declare the following to be a full, clear, and exactdescription of the invention, reference being had to the accompanying drawings, which form part of this specication, in which- Figure l is a plan view, partly in section,of a sewing-machine with my improvements applied thereto. Fig. 2 is a front elevation of same. Fig. 3 is a perspective of improvement and clamp, and Fig. 4 is a perspective of improvement, viewed from the rear. Fig. '5 is a perspective view of a button-hole sewingmachine with my improvements applied thereto.

My invention has relation to an attachment for button-hole sewingmachiues, whereby a button-hole is corded while being stitchedthat is to say, a cord is laid around the edge of the buttonhole on the fabric and covered by the stitching around such edge.

My invention has reference particularly to button-holes which have curved ends; and my improvements are designed to provide means whereby the cord will be curved around the ends as well as laid along the straight edges of the button-holes.

My improvements consist in the peculiar construction and combinations of parts hereinafter fully described.

In carrying my invention into effect I provide a bracket or plate which is designed and adapted to be securely fastened to the front of the head of a sewingnnachine. On this bracket there is a rod,which is hinged at its upper end and provided at its lower end with an eye, which forms a guide for the cord. Said rod has connected. to it a spring, which tends to draw or push it one direction. There is also provided a pin or stud, against which the rod rests, and by means of which it is retained in position against the pull of the spring until, by means of other devices presently to be described, said rod is pushed away from its seat on said pin and is moved by the action of the spring. The pin or stud just mentioned is adjustable, for a purpose hereinafter described.

The means described for pushing the rod away from the retaining stud or pin consist of the following parts: There is a lever pivoted on the back of the bracket or plate and having at one end a pin or stud which projects through a slot in said bracket. The other end of said lever is connected by alink or connecting'rod with a moving part of the machine, so that when one side of the buttonhole has been stitched and a change is made to stitch the end of such button-hole the lever is vibrated, pushing its pin against the cord-rod and moving the latter away from the retaining stud or pin. On the front of the bracket there is an other stud or pin, which limits the movement of the cord-rod under the influence of the spring and forms a second rest for said rod, and a guard which guides said rod toward the bracket.

The object of moving the cord-rod is to curve the cord around the end of the button-hole and to cause the cord to lead the needle when the second side of the button-hole is being stitched.

Referring to the accompanying drawings, A represents the cloth-plate of a button-ho1e sewing-machine, which latter may be of any suitable construction having means for causing the cloth to bemoved underneath the needle while the latter is stitching the button-hole.

Any suitable or usual mechanism, not necessary to be here described, may be provided to enact with the needle in forming the stitch.

B represents a clamp, which holds the cloth or material in which the button-hole is made and moves it while the button-hole is being stitched. Said clamp is connected with a cross head, G, on the machine by means of an arm, G, fastened to a slide or block, D, which moves in a slot, 0, in said crosshead. In the operation of the machine the clamp moves in the direction of the arrow at until one side of the button-hole has been stitched, and then moves in the reverse direction to stitch the other side of the bntton-hole, laterally recip-,

rocating during both of said movements so as to produce an overseaming or button -h0le stitch.

The construction whereby the clamp is moved and the stitch produced forms no part of my invention, and is not claimed by me.

E represents a bracket or plate securely fastened to the front of the head F of the sewing-machine. On this bracket there is mounted a rod, G, which is hinged at its upper end in the bifurcated end of a swivel, H, so that said rod may be swung outwardly to and from the plate E, and. also in a plane parallel with the latter or line of feed.

I represents a spring connected to the rod G, and also to a screw, 1', on the plate E. Said spring is a pull-spring and tends to constantly draw the rod G in the direction of the arrow K is a pin or stud projecting from the bracket E, against which stud the rod G rests, as hereinafter mentioned.

L is another pin or stud on the plate E, against which said rod G rests when moved away from the pin K.

M is a wire guard projecting obliquely from the plate E, and forming a guide for the rod G as the latter movesfrom the pin K to the pin L.

N is a lever fulcrumed centrally on a stud, n, on the back of the bracket E. One end of this lever-carries a pin or stud, a, which projecis through a slot, 6, in the bracket E in line with the rod G, when the latter is resting against the pin K, so that when said lever is swung or rocked the pin it pushes the rod G outwardly beyond the end of the pin K. The opposite end of said lever has a hingeconnection, of, with a link or connecting-rod, 0, whose inner end is bent, as shown at 0, and rests in contact with the inner side of the cross-head C. The lower end of the rod G is bent around or curved, so that its eye g comes inside of the needle or between the line of feed or path of the needle and the cross-head O and in advance of the needle, in order that the cord i, which passes through said eye, may rest upon the cloth onthe inner edge of the but:- ton-hole in advance of the needle. Said cord comes down from a spool or bobbin, Q, through a guide, q, and thence through the eyeg of the rod G.

In operation, in starting a button-hole, the guide-rod G rests against the pin K, as shown in Fig. 3, the clamp and needle occupying the positions shown, the needle being at one end of the buttonliole slot or opening I) in the clamp-shoe B. As the stitching proceeds the clamp and cloth move in the direction of the arrow as, reciprocating laterally at every stitch, whereby the first side of the button-hole is stitched. \Vhen the clamp has moved so far that the needle is at the other end of the slot in the clampshoe, said clamp is then moved laterally or inwardly, so as to cause the stitching to proceed upon the otherside of the button-hole, said movement being effected by a. lateral or inward movement of the cross-head 0. This lateral movement produces apull on the link or connecting-rod O, as its end 0 is in contact with the inner side of the cross-head, and draws the adjacent end of the lever N, moving the opposite end of said lever ont- Wardly, so that its pin it pushes the rod G outwardly from the bracket E, releasing it from its rest on the pin K. Said rod is then pulled backwardly by the spring I, being guided inwardly toward the bracket E by the guard M until it meets and rests against the pin L. As the rod G swings outwardly it carries the cord across the rounded end of the button-hole, and as 'it instantly swings in wardly toward the plate or bracket E the cord is curved around the eye or rounded end of the button-hole comformable to the curve of the latter. The movement of the rod outwardly and then inwardly brings it back into the plane which it formerlyoccupied, but on the opposite side of the needle, so that its cord again leads the latter onthe reverse move ment of the clamp which occurs in stitching the second side of the button-hole. The stitching of the other side of the button-hole is now continued until concluded, after which the rod G is again restored by manual operation to its normal position against the pin K, ready to stitch another button-hole. The pin K has a bearing in a boss, Eton the bracket E, and is held by a set-screw, it, so that it can beadjusted to project more or less from said bracket, the extent of projection determining the distance the rod G will be moved laterally at the rounded end of a' button-hole, as a variation in such distance is desirable in button-holes of different sizes or varying widths at their rounded ends.

As my attachment may be obviously applied to other forms of sewing-machines than those having a cross-head, O, my invention is not limited to any particular form of sewing-machine, and. any other means than such crosshead which will operate to effect a movement to throw the cord-rod off its seat at the end of the button-hole, or when the first side of the latter has been stitched, will answer the same purpose. So, too, a push-spring may besubstituted for the pnll-spring 1.;

Vhat I claim as my invention is- 1. The combination, with the bracket E, adapted and designed for attachment to the head of a sewing-machine, of the hinged cordrod G, forming a guide for the cord, pins or rests K and L, spring I, and imeans for moving said rod away from contact with the pin or i rest K, substantially as shown and described. 2. The combination,with hinged cord-rodG,

pins or rests K and L, and spring I, of lever N,

having pin n, and link or connection O,whereby said cord-rod is moved awayfrom contact with the pin or rest K, substantially as shown and described.

3. The combination, with bracket or support E, hinged cord-rod G, spring I, and pins K and L, of the guard M, whereby said ll'Od,

described, between said rod and the part which i Q moves the clamp, whereby when the clamp is moved laterally to cause the needle to stitch the second side of the button-hole said rod is moved around the needle, substantially as shown and described.

5. In combination with the hinged cord-rod G and bracket or support E, the adjustable pin or rest K, substantially as shown and de scribed.

6. The eombinatiomwith the head and stitchforming mechanism of a sewing-maehine, a clamp on said machine for holding and moving material while being stitched, and mechanism for moving said clamp, of the bracket E, hinged cordrod G, spring I, pins or rests Kand L, guard M, lever N, having pin n, and

connecting-rod 0, attached to one end of said lever and engaging vith the claxnpqnoving mechanism, substantially as shown and de- 20 scribed.

7. The combination, with the needle and button-hole clamp of a sewing-machine, ofahinged rod, G, forming a guide for a cord, and operating mechanism, substantially as described, whereby it may be moved outwardly or laterally, and also in a plane parallel with the line of stitching to transfer it from one side to the other of the needle, in order that its cord may lead the latter in stitching both sides of the button-hole, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this 15th day of April, 1886.
